Catabolite induction

Vedclass · Answer

(A) The lactose operon is regulated by the presence or absence of glucose through a mechanism known as catabolite repression or catabolite induction. When glucose levels are low,the concentration of cyclic $AMP$ $(cAMP)$ increases. This $cAMP$ binds to the Catabolite Activator Protein $(CAP)$,forming a $cAMP-CAP$ complex. This complex binds to the promoter region of the $lac$ operon,facilitating the binding of $RNA$ polymerase and enhancing transcription. Therefore,the operon is sensitive to glucose levels via this catabolite-mediated process.
